针对某飞行器地面电源故障诊断中的特点和难点,运用D-S证据理论对其电气故障智能诊断中的应用进行探讨。本文首先介绍D-S证据方法的基本理论,然后以某飞行器地面电源中的电气故障为例建立故障特征库,最后利用D-S证据理论对该飞行器地面电源故障融合的结构、算法等进行了仿真研究,取得了满意的效果。
Aiming at the characteristics and difficulties in the ground power fault diagnosis of an aircraft, the application of D-S evidence theory to the intelligent diagnosis of electrical faults is discussed. In this paper, the basic theory of DS evidence method is introduced firstly. Then, the fault signature database is established by taking an electrical fault in the ground power of an aircraft as an example. At last, the structure and algorithm of ground power fault fusion of the aircraft are simulated by using DS evidence theory. Satisfied with the results.
